nmakro, The power system of the RBBB is really simple so everything is connected together. You should be very careful though with those batteries. If you hook them up in reversed polarity to the RBBB very bad things are going to happen. Also you definitely don't want them connected at the same time ...

nmakro, I'm puzzled. You are measuring 4.8 volts at power pins from ground? One word of warning on those batteries - those are rather large batteries and they really should have a fuse or PTC or something in the circuit - if you hook them up backwards at the RBBB you are going to vaporize the backwa...

Do you have any other FTDI connect devices to try? But this setup works with other chips right? Also you mailed us your name and address right? I didn't see it , with cursory look through the sales at moderndevice ... email box. Maybe just send us the same message again. Put "forum issue" in the ema...

Sorry I thought my shipping person would catch that - stand by - trained engineers are working on your problem. Meanwhile I just remembered that the "Friend" uses RTS line for reset. Monitor the reset line with a multimeter and see if you see it toggle it all on upload? Try this and report back: If ...

Tony, Sorry for the Really slow reply I'm missing the suggestion. They will short-cut if the RBBB is pushed into a breadboard. People have been using these on breadboards for years - all the pins are in a row - how can pins short out? OK - it think you're referring to the input power holes. They wer...

librav, Does your COM port appear / dissapear when you plug / unplug the friend? That will confirm driver issues. Latest drivers are here: http://www.ftdichip.com/Drivers/VCP.htm Are you using UNO setting on Arduino? It could also be Duemialanove if it's an older board from somewhere - we switched J...

HillyOTM, The type of LEDs don't matter. Confirm voltages at the chip with a multimeter. http://arduino.cc/en/Hacking/PinMapping Confirm that the chip is in the socket in correct direction (look at the silkscreen on the board for the divet). Confirm that the reset line (pin 1) is high and goes low w...

Hilly, The light on the RBBB is a pilot light - just means power is good. Try hooking up an LED to pin 13 and hitting the reset button. If you see a flash then, it means that there is a bootloader on the chip. If you bought the board recently, it has Uno (Optiboot) bootloader. If it was manufactured...

dfaulks, I'm sorry to disappoint you but we don't really do much development in Windows at all. We're mostly a Mac and Linux shop so Visual Studio is a black hole to us. Try posting your question on the Arduino forum and see if you get some response. You seem to have gotten the data into your window...

Shoot - I could swear I had updated the forum, but apparently not. New code is on the product page, updated for Arduino 1.0. http://shop.moderndevice.com/products/humidity-and-temperature-sensor I also remember doing this much earlier but apparently never posted the code to the website. Thanks for b...

Elina, Sorry I can't understand what is going on in your thread. No voltage output on the sensor? Did you put a multimeter on the output? If you put a meter on the output and can't see it change, the odds are that the sensor is damaged. That particular sensor doesn't suffer reverse polarity very wel...

Carloscoleman, Are you having issues uploading? Try try the UNO board setting - if no luck maybe you have an older board. Try the Duemilanove setting. Still no luck? Put an LED from pin 13 to ground through a 220 - 1k resistor. Push the reset button and see if the LED flashes - that's the bootloader...

It's slightly weird that it works with older bootloader but not the new one. The upload speed and timing are different on Optiboot which probably makes the floating logic line issue problematic. I'd say confirm that the logic line pin is not floating on the BUBII and that the headers are soldered on...
